Conservation Drones

The orangutan is the only great ape found outside Africa but the species native to Sumatra is critically endangered. Illegal palm oil plantations are slowly eating into the orangutans' habitat and pushing them into the hands of poachers.

"When a palm oil company goes in, they completely destroy the forest and everything that’s living there," explains Ian Singleton of the Sumatran Orangutan Conservation Program. "There may be a tree left with a mother orangutan and her baby so they'll chop down that tree, club her to death and take her baby home."

One way to tackle this deforestation by palm oil agribusiness is to monitor and report their illegal activities but in large areas such as the Leuser Ecosystem in Sumatra, that has proven virtually impossible - until now. A unique collaboration of conservation NGOs have now begun surveying illegal clearing of protected forests with the help of drones.

Capturing high-resolution aerial footage of the devastating impact of palm oil is proving powerful and has already helped bringing perpetrators to justice.

Urban Mining

Mining for rare and precious metal is a messy process. It is not only very expensive, but has a huge environmental cost, resulting in the contamination of land and water and a loss of biodiversity.

But these metals are key components in modern technology, and as our desire for electronics and electrical equipment soars, our throwaway culture is seeing more and more of these valuable, finite resources being lost to landfill. It is estimated that only 13 percent of electronic and electrical waste that is generated each year worldwide is currently recycled.

Russell Beard travels to Belgium, to meet a network of recycling organisations dedicated to recovering these precious metals, in a process known as urban mining.
